METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING DEMODULATION REFERENCE SIGNAL

Abstract: methods, apparatuses, and systems described herein generally relate to a reference signal generation and mapping. for example, a method comprises determining a first set of antenna ports for a demodulation reference signal (dm-rs) transmission; determining, based on the first set, a frequency index associated with four adjacent resource elements, wherein the four adjacent resource elements correspond to two adjacent symbols in a time axis and to two adjacent subcarriers in a frequency axis; generating, based on a first orthogonal cover code and a second orthogonal cover code, a dm-rs associated with the first set of antenna ports; and transmitting, via a mapping to the four adjacent resource elements, the dm-rs associated with the first set of antenna ports.
